Web site Floorplanner is a web-based floor planning application that creates complex layouts to help you design the layout of any room in your home. Floorplanner runs in Flash and employs a simple drag-and-drop interface to customize virtually anything you can imagine, making it fairly easy to replicate any room (to scale, even) and try out different layouts. We've suggested a fewlayouttools for floor planning in the past, but Floorplanner is by far the most robust. A free account should be enough for most weekend remodelers, but if you need a lot more, Floorplanner has several different premium options available.
